1. Prepare the box first, and then fill it with rice, as shown in the figure.

2. Put the bananas in and start burying them in the rice, as shown in the figure.

Then you can bury the banana roots in the rice, you don't need to buy them all.

Then cover it, seal it, and let it stand for two or three days to see if it is cooked. Rice can ripen bananas.
